Introduction
Type B208,CB-200 is a sprag type free wheel not self-centring. It is therefore
necessary to place one or two bearings next to the free wheel so
that the outer race can rotate centrally to the inner race.
The bearings to use next to the free wheel are written in the
following table.
A key will transmit the torque between outer ring and the shaft.
the tolerance of the housing bore must be h7.
The sprags work on the shaft made by the user which must be
realized following these indications:
1) carburized depth after grinding 0,6 mm
2) surface hardness of hrc58-62
3) core hardness of hrc35-45
4) surface roughness must not exceed 6,3 μm
5) maximum shaft taper 0,01 mm per 50 mm length
CB-200 series can be lubricated with grease or oil but they must
not have EP additives

Product Picture
Installation and Usage
1.B200 Series Cam Clutch is shaft mounted, so the shaft on which
the clutch is mounted must be hardened to Rc 56-60 and 1.5 mm case
depth after grinding. Grind to 1.5S (16micro-inch) finish. The
taper of this shaft should not exceed 0.01 mm per 50mm.
2. For installation of the clutch mount the clutch with bearings at
both sides or on one side in
order to obtain concentricity between the shaft and the clutch
outer race and to take up radial
or thrust loads which may work on the outer race or the shaft. See
the installation example.
3. The clutch should be mounted on the shaft by rotating it in the
direction marked by the arrow
shown on the clutch plate. Do not apply shock to the clutch by
hammering.
4. The clutches have the same outside diameters as the bearings
shown in the table above. Bore tolerance of the housing in which
the clutch is assembled should be within the range shown in the
table below.
5. For indexing, oil lubrication is recommended.
6. Concentricity of the housing bore and shaft should be within
0.05 mm.
7. Key profile should be in accordance with JIS B1301-1959
